Abstract

Un aparato de comunicacion multiportador y similar en donde se suprime la cantidad aritmetica requerida para calcular un peso de recepcion a traves del cual una senal multiportadora se va a multiplicar, mientras se mejora la caracteristica de recepcion para la senal multiportadora. En el aparato, una parte generadora del peso de transmision de subportador (513) genera un peso de transmision de cada subportador, con base en la informacion de canal de cada subportador recibido de la parte generadora de informacion de canal (511) y un peso de recepcion de cada grupo subportador recibido de una parte generadora de peso de recepcion de grupo subportador (512). La parte generadora del peso de transmision de subportador (513) captura los pesos de transmision generados de los subportadores respectivos a los multiplicadores correspondientes (522).
